SAFEGUARDS
Important Information
EXAMPLE OF ANTENNA GROUNDING ACCORDING TO
NATIONAL ELECTRICAL CODE INSTRUCTIONS CONTAINED
10. Grounding or Polarization - This video product is equipped
with a polarized alternating - current line plug (a plug having one
blade wider than the other). This plug will fit into the power socket
only one way. This is a safety feature. If you are unable to insert the
plug fully into the outlet, try reversing the plug. If the plug should still
fail to fit, contact your electrician to replace your obsolete outlet. Do
not defeat the safety purpose of the polarized plug.
11. Power Sources - This product should be operated only from the
type of power source indicated on the marking label. If you are not
sure of the type of power supplied to your home, consult your
appliance dealer or local power company.
12. Power-cord Protection - Power-supply cords should be routed
so they are not likely to be walked on or pinched by items placed upon
or against them. Pay particular attention to cords and plugs, convenience receptacles, and the point where they exit from the appliance.
13. Lightning - For added protection for this product during a
lightning storm, or when it is left unattended and unused for long
periods of time, unplug it from the wall outlet.
14. Power Lines - An outside antenna system should not be located
in the vicinity of overhead power lines, other electric light or power
circuits, where it can fall into such power lines or circuits. When
installing an outside antenna system, extreme care should be taken to
keep from touching such power lines or circuits as contact with them
may be fatal.
15. Overloading - Do not overload wall outlets and extension cords
as this can result in risk of fire or electric shock.
16. Object and Liquid Entry - Never push objects of any kind into
this product through openings as they may touch dangerous voltage
points or short-out parts that could result in a fire or electric shock.
Never spill liquid of any kind on the product.
17. Servicing - Do not attempt to service this product yourself as
opening or removing covers may expose you to dangerous voltage or
other hazards. Refer all servicing to qualified service personnel.
18. Damage Requiring Service - Unplug this product from the wall
outlet and refer servicing to qualified service personnel under the
following conditions:
a. When the power-supply cord or plug is damaged.
b. If liquid has been spilled, or objects have fallen into the
product.
c. If the product has been expesed to rain or water.
d. If the product does not operate normally by following
the operating instructions. Adjust only those controls that are covered
by the operating instruc tions. An improper adjustment may result in
damage and will often require extensive work by a qualified technician to restore the product to its normal operation.
e. If the product has been dropped or the cabinet has been damaged.
f. When the product exhibits a distinct change in performance - this
indicates a need for service.

hazards.
20. Safety Check - Upon completion of any service or repairs to this
product, ask the service technician to perform safety checks to determine that the product is in proper operating conditions.
21. Outdoor Antenna Grounding - Before attempting to install this
product, be sure the antenna or cable system is grounded so as to
provide some protection against voltage surges and built-up static
charges.
a. Use No.10 AWG (5.3mm ) copper, No.8 AWG (8.4mm (aluminum,
No.7 AWG (10mm ) copper-clad steel or bronze wire or larger, as
ground wire.
b. Secure antenna lead-in and ground wires to house with stand-off
insulators spaced from 4 feet (1.22m) to 6 feet (1.83m) apart.
c. Mount antenna discharge unit as close as possible to where lead-in
enters house.
d. A driven rod may be used as the grounding electrode where other
types of electrode systems do not exist. Refer to the National Electrical
Code, ANSI/NFPA 70-1984 for information.
e. Use jumper wire not smaller than No.6 AWG (13.3mm ) copper or
equivalent, when a separate antenna grounding electrode is used.

DESCRIPTIONS
and Specifications
Description
The TA-52 is a 52 dB gain UHF/VHF/FM
broadband distribution amplifier designed
to function as a reliable key component in
medium and large MATV systems. Signal
control is provided through front panel
design. The UHF/VHF input may be
combined or separated by use of a single
throw switch. Low band VHF, High band
VHF and UHF frequencies have separate gain
controls and switchable 10 dB input
attenuators. Features include switchable FM
trap and -20 dB test point.
